Paul, colin and brian are waiters. one night the restaurant earns tips totalling £71.10. they share the tips in the ratio 2: 3: 4. how much more does colin get over paul?

£7.90

add the parts of the ratio 2 + 3 + 4 = 9 parts

divide £71.10 by 9 to find one part of the ratio

= £7.90 ← 1 part of the ratio

2 parts = 2 × £7.90 = £15.80 ← Paul's share

3 parts = 3 × £7.90 = £23.70 ← Colin's share

4 parts = 4 × £7.90 = £31.60 ← Brian's share

Colin receives £23.70 - £15.80 = £7.90 more than Paul

i would say c is the best answer, hope it's right!

good luck! =)
